Step-by-step solution
In arithmetic growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures. Mathematically, it is expressed as L t = L 0 + r t where L t = length at time 't' L 0 = length at time 'zero' and r = growth rate / elongation per unit time. The simplest expression of arithmetic growth is exemplified by a root elongating at a constant rate. In geometrical growth, both the progeny cells following mitotic cell division retain the ability to divide and continue
